There are two common ways to measure air velocity: by using pressure-based instrumentation or by using temperature-based instrumentation. Before we discuss the different technologies available for measuring velocity pressure, it is important to understand the basics of air velocity.
We recently met with a customer in Odessa, TX, who was having an abnormal amount of smart pressure transmitter failures in their LACT skids from one customer’s region.
Lease Automatic Custody Transfer (LACT) units are used for the unattended and automatic measurement of the quality and quantity of crude oil, typically from well head producers to purchaser, or from truck offloading into storage tanks. These sites are typically on production lease sites in remote areas. Continue reading “Adjustable Pressure Snubbers Used to Protect Instruments Against Pressure Surges in LACT Units”
